Lets do some rad stuff


One-off or small production runs are our speciality. We have supplied to MotoGP, British Superbike riders, British and world Supersport teams, and TT teams and bikes. This includes chassis and fuel tank development along with designing and supplying exhausts. We offer a full dyno exhaust development programme, custom exhausts including full systems and silencers, custom styling, sub frames, swinging arms and custom fuel tanks. We work closely with GPMS Technology who are design consultants to the motorcycle race industry.


As much as we love building motorcycles and components the best part is getting out and riding them. Our roots are in flattrack racing but there’s no motorcycle discipline left untried whether it’s our own riding or supplying bikes and components for production bikes, choppers, bobbers, vintage rides, trials bikes, trail bikes and motocross. We love riding and working on them all.


There’s nothing like the thrill of racing. We love it and have ridden in most disciplines whether it’s flattrack, road racing, enduro, motocross, desert racing or endurance events. On a professional level Co-Built have supplied components for all of these racing types as well as speedway, scooter racing and land speed competitions.
